An Algebraic State Observer for a Self-Sensing Active Magnetic Bearing System
Olga Zarina, Natalya Martyuhova, Alexey Bobtsov +1
The problem of designing a globally stable observer for a self-sensing active magnetic bearing system assuming only measurements of currents and voltages is addressed in this paper…
An Algebraic State Observer for a Class of Physical Systems
Alexey Bobtsov, Jose Guadalupe Romero, Romeo Ortega +1
In this paper we present a radically new approach to design state observers for nonlinear systems, with particular emphasis on physical ones. Our objective is to obtain an algebrai…
State Observer for the Fourth-order Model of a Salient Pole Synchronous Generator with Stator Losses: Known and Partially Unknown Input Cases
Alexey Bobtsov, Romeo Ortega, Nicolai Lorenz-Meyer +1
In this paper we study the question of how to reconstruct the state of a power system using Phasor Measurement Units (PMUs). In our previous research we proved that this question h…
Adaptive State Observers of Linear Time-varying Descriptor Systems: A Parameter Estimation-Based Approach
Romeo Ortega, Alexey Bobtsov, Fernando Castanos +1
In this paper, we apply the recently developed generalized parameter estimation-based observer design technique for state-affine systems to the practically important case of linear…
